Absolutely Brilliant. 
Even after reading reviews I was a little reluctant to buy this topper,
well I needn't have , I had the best nights sleep in a long time , it's far superior to other more expensive toppers.
I highly recommend it , really thick pure memory foam no smell and not stuck on to any other Foam .
May I add the service from Wayfair from ordering to receiving my topper was also Brilliant.  THANK YOU  WAYFAIR.  :-) 
From an extremely satisfied Customer. 
P.S  on my recommendation my Cousin has just ordered one too.
